摘要:
Actuator stem and rod end bearings having locking mechanisms are described. An example apparatus for use with a control valve actuator includes a rod end bearing having a bearing retainer and a shaft portion extending from the bearing retainer. The apparatus also includes an actuator stem having a first end to be operatively coupled to a diaphragm plate of the control valve actuator and a second end to be coupled to the rod end bearing. A locking mechanism coupled to the actuator stem or the rod end bearing prevents the actuator stem and the rod end bearing from decoupling when the actuator stem is coupled or de-coupled to the diaphragm plate.

A fabrication method for providing a relatively smooth surface associated with lightning strike protection for composite materials joined with fasteners recessed below the surface is described. The method includes coating at least one of a head of the fastener and a preformed dielectric insert with an adhesive, inserting the preformed dielectric insert into the recess such that the adhesive engages both contours of the recess and the preformed dielectric insert, and removing any excess adhesive from the surface area of the composite material and a top surface of the insert.

A connector for a container, particularly a cask, comprises a bush (14), intended to be received in an opening (11) in the container through which liquid is discharged, in use. The bush has a closed end (17) with a weakened portion (18), an inner thread (20) and an inner deformable portion (21). Sealing means (23) are intended to be disposed between the exterior of the bush and the interior of the opening at the position of the deformable portion. An insert (15) is screw-threadedly engageable within the bush so as to deform the deformable portion, thereby effecting compression, and thus sealing, of the sealing means between the bush and the container.

A rigging for moving an aircraft panel relative to an aircraft substructure includes a retaining base attached to a panel interior, and a slider rod held in contact with the substructure and adjustably engaged with the retaining base. The slider rod is manipulable from the panel exterior to adjustably engage the panel in a rigging position along a fair axis. The slider rod may include a tool appurtenance captively positioned within the riser bore that is exteriorly manipulable through a panel access port. Tool appurtenance manipulation may actuate the slider rod to adjustably engage the support hub and to move the panel into the fair position. A fit plate may be attached to the aircraft panel disposed intermediate to the retaining base, and may be adjustably attached to the aircraft panel for moving the aircraft panel into a fit position in a rigging plane.

A connection system includes a float assembly and a locking assembly. The float assembly includes a floating ring and a float retainer disposed against the floating ring. The float retainer is adapted to be secured to a first object. The locking assembly includes a locking collar and a base retainer. The base retainer is coupled to the locking collar and adapted to be attached to a second object. The base retainer includes an engagement member engaging the floating ring, with the float retainer disposed between the floating ring and the locking assembly. The locking assembly is moveable between a first configuration wherein the float retainer is moveable relative to the locking assembly and a second configuration wherein the float retainer is fixed relative to the locking assembly.
